Détails:At 16:44 PST Flight 336 took off from San Jose for a flight to Santa Ana. 48 Minutes later, the crew received a clearance for a visual approach to runway 19R. While Flight 336 approached, the controller cleared Air California Flight 931 for a runway 19R takeoff. When recognising the hazard, the controller ordered Flight 336 to abort the landing and go-around and Flight 931 to abort the takeoff. Flight 931 rejected its takeoff, but Flight 336 landed with the gear retracted. The 737 left the runway surface at 900 feet past the threshold and skidded another 1170 feet before coming to rest 115 feet to the right of the centreline.

Probable Cause:

PROBABLE CAUSE: "The captain’s failure to immediately initiate a go-around when instructed to do so by the tower’s air traffic controller and his subsequent failure to correctly execute the specified go-around procedure which resulted in the retraction of the landing gear after the aircraft touched down on the runway."
